An unmissable milestone for fans of Sir Terry Pratchett: the first SF novel in over three decades in which the visionary inventor of Discworld has created a new universe of tantalizing possibilities—a series of parallel “Earths” with doorways leading to adventure, intrigue, excitement, and an escape into the furthest reaches of the imagination.

The Long Earth, written with award-winning novelist Stephen Baxter, author of Stone Spring, Ark, and Floodwill, captivate science fiction fans of all stripes, readers of Kurt Vonnegut, Douglas Adams, and Carl Hiaasen, and anyone who enjoyed the Terry Pratchett/Neil Gaiman collaboration Good Omens.

The Long Earth is an adventure of the highest order—and an unforgettable read.

Sir Terry Pratchett was the internationally bestselling author of more than thirty books, including his phenomenally successful Discworld series. His young adult novel, The Amazing Maurice and His Educated Rodents, won the Carnegie Medal, and Where's My Cow?, his Discworld book for “readers of all ages,” was a New York Times bestseller. His novels have sold more than seventy five million (give or take a few million) copies worldwide. Named an Officer of the British Empire “for services to literature,” Pratchett lived in England. He died in 2015 at the age of sixty-six.

Stephen Baxter is an acclaimed, multiple-award-winning author whose many books include the Xeelee Sequence series, the Time Odyssey trilogy (written with Arthur C. Clarke), and The Time Ships, a sequel to H. G. Wells's classic The Time Machine. He lives in England.
